PATENT OFFICE YIELDING SEAT sUrroR'r Application filed November 11, 1927. Serial No. 232,570.

The present invention relates to seats which are supported yieldin-gly to ushion forces exerted upon the supporting urface by the weight carried by the scat. These constructions have previously been adapted for use upon various types of seats and chairsand the present invention deals more specifically with the. type known as deck chairs or seats which are readily portable.

Vhere the construction of the chair involves a. central pedestal which receives the thrust of the supported weight and is braced laterally to maintain the structure in an upright position, effective cushioning within the standard mounting structures is a difficult thing to attain. It has been thought heretofore that the structure would have to be considerably altered to include a proyision for such cushioning and very little progress has resulted in this line. (a I The present invention proposes to incora known form of pedestal chair cushioning the weight carried by the chair, particularly for weights approximating those of occupants of the chair. The'support for the chair is altered but little,'and the elements constituting the cushioning structure are sim ple in construction and easy to-assemble.

- Other objects and advantages of the invention will appearas the description procceeds I and reference will now be had to the accompanying drawings wherein:

Figure 1 is a view insection showing a preferred form of the invention, wherein a seat is mounted yieldingly against movement, both horizontally and vertically.

Figure 2 is a segmental view 7 in section showing a modified form of the support shown in Figure 1.

Referring particularly to Figure 1, an indicates the floor or deck upon which the chair is to be mounted, A plate Z), having a downwardly extending socket or neck b is carried by the floor and is provided with a cap .b" at its lower extremity. This cap is secured to the neck portion Z)" by means of suitable bolts b and within the neck portion, a sleeve 0 is n 2 I carried. This sleeve is provided with an enlarged annular portion 0 formed with a seat 0 to, receive an annular block d of yielding non-metallic material, such as rubber. The block may be confined under compress1on by means of a washer d whlch is urged against the upper portion of the block (1 by means of a nut 0Z Between the cap b and neck b, annular recessed portions 6 are provided. These recesses receive the annular flange e of a block of yielding non-metallic material e which is provided with a lower extension 6 and a socket 0 At f is indicated the base for a seat or chair and carried by this base is a downwardly extending pedestal 9 provided with a restricted lower extremity g for engaging the socket e It will be seen from the above description, that downward movements of the seat are resisted by the block 0, the force being transmitted to the socket 6 through the annular flange 6. Lateral movements of the seat are resisted by the annular. block (2 at the top of the sleeve 0.

In the modificationshown in Figure 2, the downwardly extending pedestal g, with its restricted portion 9, is carried by a block of yielding non-metallic material h which may be cutaway as at k to permit flowing of the material when a weight is carried upon the seat. In this modification, the yielding material resists downward movement of the ped estal 9 under compression, whereas, in the preferred form, the weight is carried by the yielding material which is under a combined sheer and tension.

It has been found that the above construe-t tion is very effective in providing a fully cushioned seat and is particularly useful in connection vwith deck chairs and the like, wherein-the structure is simple and light.

I claim as my invention: 1

1. A vertical tube, a pedestal disposed loosely therein, a housing at the upper end of the tube, yielding material in the housing engaging the pedestal near its upper end, and a yielding support in the tube near its lower end engaging the lower end of the pedestal.

2. A seat, a pedestal therefor, a sleeve, a yielding non-metallic collar carried by the sleeve at its upper end to cushion lateral movements of the pedestal, means to position the sleeve vertically, a cap on the lower extremity of the positioning means, means to secure a block of yielding non-metallic mate 5 rial between the cap and the positioning means, and means to seat the pedestal in the cushioning means. 1

3. A seat, a pedestal carried thereby, a O sleeve, :1 yielding non-metallic collar carried by the sleeve at its upper end to cushion lateral movements of the pedestal, means to position the sleeve vertically, acap on the lower extremity of the positioning means, annular recesses in the cap and positioning means, a block of yieldingnon-metallic material having an annular flange, means to secure the capto the positioning means with the flange in the recesses thereof, and means to seat the pedestal in the cushioning means.
